Yes, it is true that millennials are more open and accepting of gender identities but there is more to it than the clothes they wear.

LGBTQ rights activist and writer Jacob Tobia released a response to the cover on Cosmopolitan wherein they talk about their struggles with identifying as genderqueer and finally feeling accepted by their peers.

"Let me spell it out for you: Unlike how this new Vogue cover shoot presents it, the lived experience of being gender-nonconforming is rarely that fun and glamorous," Jacob points out.

They even noted that the shoot was appropriating the efforts and stands of gender-fluid people, "This, then, is flagrant cultural appropriations-taking symbols and ideas that were created by a group of oppressed people and using them, without credit, collaboration, or compensation, to elevate people who are not part of that oppressed group."

Vogue eventually released an apology saying, "The story was intended to highlight the impact the gender-fluid, non-binary communities have had on fashion and culture. We are very sorry the story did not correctly reflect that spirit-we missed the mark."

So what then does it mean to be gender-fluid?

They don't identify with being men or women, they see themselves as somewhere in the middle of the spectrum.

Some non-binary people don't identify with a gender at all. It can be an ongoing process of figuring out their identity and expressing their true selves, whatever that might be.
